I'm sure the intentions in making this comic were good, but you really shouldn't read "Spike" and "Willow" at the starting point of Season 9, alongside "Buffy" and "Angel & Faith". You sort of need the context first of Spike's and Willow's involvement in the main titles before their minis started.

We'll see what this actually looks like, I like the idea of having it as a collectors item thing, but I don't collect comics, only trades really so I'm going to wait to see what the actual package looks like.
